1136473 - Harmony Proxy object with array as target always returns length of 0

Status: RESOLVED DUPLICATE of bug 1111604

(Core :: JavaScript Engine, defect)

Description

[Tom Horne]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150222232811

Steps to reproduce:

Run the following:

var ar = [1, 2, 3];
var prox = new Proxy(ar, {});
console.debug('original.length: ', ar.length);
console.debug('proxy.length: ', prox.length);



Actual results:

console output: 

original.length: 3
proxy.length: 0



Expected results:

Since the handler has no "get" property, getting a property from the proxy should return the same result as getting it from the target. Instead, proxies with arrays as targets always return 0 for the length property.
